3 Claims.

This invention relates to structure for protection against the sun andother elements and particularly to an umbrella-like assembly that isadapted for use with farm implements, such as combines, wherein theoperator is almost continuously aggravated with dust accumulation havinga tendency to center about the platform upon which he operates.

It is the primary object of the present invention to provide a hood-likestructure mounted upon an upright standard above the position of anoperator of a farm implement, the structure being in turn provided withmeans for directing a current of ltered air downwardly toward theoperator not only for the purpose of coolness but more particularly toevacuate the space around the platform of undesirable dust.

The most important object of the present invention is to provide aprotecting hoodV of the aforementioned type wherein a canvas or otherflexible cover is supported in a frusto-conical manner and provided withan air intake at the apex thereof, there being means adjacent the intakefor directing Ia current of air downwardly into the hood and thencearound the machine operator to be protected.

Another object of the present invention is` to provide means Within theaforesaid hood adjacent the air inlet opening for confining the currentof air within a predetermined path of travel.

A further object of the present invention is to provide a protectinghood as above set forth wherein the inlet opening of the cover itselfhas a dome-shaped filter member in communication therewith exteriorly ofthe hood for cleaning the incoming air prior to reaching the operator.

Other objects include the way in which the supporting standard isrendered extensible whereby the hood may be adapted for other uses; themanner of providing a quickly releasable attaching means for the canvascover as well as the filter itself; and other more minor details ofconstruction capable of rendering the device sturdy, inexpensive andhighly efficient for its intended purposes.

It is common knowledge to those who have had experience operatingagricultural implements that the dust factor is one of the mostharassing problems. A farm implement operator is not particularlyconcerned about the heat of the sun or even rain and other elements; butthe constant breathing of various types of dusts always proves to be ahealth damaging factor. Various attempts have heretofore been made toprovide umbrellas, for instance, particularly adapted to be used on farmimplements; and, While such structures are helpful in protection againstthe sun, for the most part use thereof has been abandoned. The reasonfor such abandonment of a protecting umbrella lies in the fact that thesame enhances the collection of dust adjacent thereto. In any event,when an umbrella-like protecting means is used, dust that is collectedadjacent the operator,

and Within the umbrella does not have the opportunity to escape and,therefore, makes the operating conditions worse than if no protectionmeans is used at all.

As will hereinafter appear, the structure forming the subject matterhereof removes the abovementioned difficulties, permits the use of anumbrella for protecting the operator against the heat of the sun, andnot only keeps the air about the operator clear of dust but feeds aconstant supply of filtered air to the operator and, at the same time,lends an element of coolness.

The protecting hood about to be described has been shown in Fig. lmounted upon a conventional combine It, but it is manifest that the usethereof is not intended to be limited to such implements or devices.Combine il! has an operators platform i2 upon which the operator eitherstands or sits to control the combine lll and/or the tractor motivatingmeans therefor. Combine Il] is, also, provided with a bin lll into whichthe grain being harvested is conveyed by means of a. hopper I6 leadingfrom the usual conveyor.

The protecting hood forming the subject matter hereof includes anextensible standard broadly designated by the numeral t8 having a pairof sections 2B and Z2, the latter of which is: telescoped within thetubular section El! for free, sliding movement therein. The lowermostend of the section 2!) has an outturned base flange 24' that may beadapted in any suitable manner for attachment directly to the platformI2. The uppermost and innermost section 22 is selectively held in thedesired position by the means of a pair of wing bolts 26 and 28, thelatter being threadably carried by the section and extending intoengaging relationshipl with the section 22 as shown in Fig. 4.

Section 22 is further held against downward movement by a collar 30circumscribing the same, and it is within this collar that wing bolt 25is mounted for releasably holding the collar 36 attached to member 22.Collar normally rests upon the uppermost end of the section 25, as isclearly shown in Figs. 1, 3 and 4.

The uppermost end of the standard I8 and, accordingly, the member 22 hasa continuous frame piece 32 secured directly thereto by welding orotherwise, said frame piece 32 being preferably circular as shown inFig. 2. Frame piece 32 is additionally supported by means of a number ofangularly-disposed brace rods 34 extending from the member 22intermediate the ends thereof and converging outwardly as the framepiece 32 is approached.

A plurality of elongated rib members 36 have the lowermost ends thereofwelded or otherwise secured directly to the frame piece 32. Ribs St areuniformly arranged about the circumference cf frame piece 32 and extendradially inwardly and upwardly at an angle to join at the uppermost-ends thereof by rivets, bolts or the like 3e to a tubular member 46.Tube 46 is preferably cylindrical and has both ends thereof open. Thepoint of attachment of ribs 36 is adjacent the uppermost end of the tube40.

An L-shaped, annular flange 42 is secured to the outermost face of thetube 45 directly above the ribs by means of bolts 44. The flange member42 serves a three-fold purpose. Firsty flange 42 serves to mount aplurality of upstanding, U--shaped supports 46 for a lter 43. The freeends of the legs of all of the U-shaped members extend between theflange 42 and the outermost face of tube 4l) and are clamped in place bymeans of the bolts 44. Supporting members i6 are relatively crisscrossed as shown in Fig. 2.

Secondly, the L-shaped flange member 42 serves to receive and supportthe apex end of a flexible hood 55) that is substantially frustoconicaland has an opening at its apex that is of substantially the samediameter as flange 42 and that is defined by a continuous piping 52.Piping 52 receives a draw string 54 which, when pulled tightly about theflange 42, rigidly yet removably secures the uppermost apex end of thehood 55 in place. The material for hood 5@ may be of canvas, as is aconventional practice, or other suitable materials capable of shuttingout the sunfs rays..

The base end of the hood 55 completely circumscribes the. circular framepiece 32 and extends downwardly therefrom into a continuous flap 56.Flap 56 has a separate piping 58 secured thereto that is continuous anddirectly underlies the circular frame piece 32 in the manner indicatedin Fig. 5.

A draw string 6) is threaded through the piping 53; and, when the sameis drawn tightly beneath the frame piece 32, the hood 56 is pulled tautbetween the frame piece 32 and the tubular member 4t. The lowermost edgeof the flap 56 has a relatively heavy hem 62 for holding the nap 5B in avertical, depending relationship to the frame piece 32.

The ange 42, also, serves to mount the dome- 4 shaped filter 48. Filter48 is formed from a relatively ne mesh, foraminous material, such asfabric, and has its lowermost open end provided with a piping 64 thatis, also, provided with a draw string 66. Piping 64 and string 66circumscribe the ange member 42; and, when drawn tightly, filter 48 isheld in place over the supporting members 46.

An electric motor B3 is mounted within the tubular member 40 through themedium of a bracket 16 with its drive shaft disposed vertically andprovided with a fan l2 rigidly secured thereto. The blades of the fan'l2 are formed to cause a downward movement of air through the tubing4i), when motor 58 is energized through the medium of a battery 'I4 orlike source of electrical energy. Electrical conductors 16 extend fromthe motor 68 through the tube 45 and downwardly along one of thesupporting ribs 35 to which conductors 16 are attached. A switch i8controls the circuit and flow of electrical energy from battery 'I4 tothe motor 68.

It is noted that the entire protecting hood is mountable upon theplatform I2 with the protecting covers 56 directly overlying theoperators position. Accordingly, the cover 56 affords shade for theoperator, and he is free to utilize the motor 68 as desired bymanipulation of switch 13. When dust tends to collect about the platformi2 and particularly within the cover 56, energization of motor 63 and,therefore, rotation of fan t2, will cause a current of air to bedirected downwardly through the lowermost open end of tube 45 to theoperator on platform l2.

The airthat, is moved by fan T2 emanates irez-.n above the cover 56,after first passing through the filter 48. Accordingly, the air that isdirected to the operator, once cover 56 has been evacuated of dust, ispure and clean. Filter 4B being disposed entirely above the cover 5Grenders the same fully exposed to air above the cover 55; and, whetheror not dust is prevalent above cover 50 is immaterial, since filter 48will prevent entrance thereof into the tube 49.

By making the standard E3 extensible, i possible to adapt the protectingmeans hereo for an altogether diierent use in the shown by dotted linesin Fig. l. In the event of sudden rain, the operator can dispose thecover 56 above the grain bin 4 and thereby protect the grain therewithinagainst wetting'. While the nlter 48 might permit some entrance of`incisture, it is contemplated that the same be of a rather fine meshand, accordingly, the amount of moisture that will reach the grain inbin i4 will be negligible.

Obviously, it is within the scope of any mcchanic to provide a closurefor the tube 43 either above or below the motor 58, if desired, andadapted to be used when the protecting hood is to be utilizedexclusively as a rain shield. Other changes and modifications are, also,manifestly within the spirit of this invention; and those that fairlycome within the scope of the appended claims are contemplated hereby.

The lower or outlet end or tube is preferably provided with circularlouvers 4i to effectively diffuse the air over the operator and therebyremove dust over a relatively large area.
